Good idea. Was a quick fix to solve a bug. Will update soon and commit changes.

Accepted Answer

One more improvement to avoid flickering. A variable to disable refresh. ---------

  1. include "N5110.h"

bool lcdrefresh=true;

...

function to refresh the display void N5110::refresh() { if (!lcdrefresh) return; ... ---------

Then we can use something like this:

lcdrefresh=false; lcd.clear(); lcd.printString(s1,0,0); lcd.printChar('$',39,0); lcd.printString(s2,WIDTH-strlen(s)*6+1,0); lcd.printString(s3,0,5); lcdrefresh=true; lcd.refresh();
